  • a common digital right is the unlimited digital right, which gives its proprietor access to content, to which the right is associated, an unlimited number of times.
  • This access can include various different types of access, for example “play”, “copy”, “burn to CD-R”, “transfer”, “download” etc.
  • a typical digital right associated with audio content is “play unlimited”.
  • limited digital rights are also common, giving its proprietor access to content, to which the rights are associated, a limited number of times.
  • This access can also include various different types of access, for example “play for 24 hours”, “copy once”, “burn to CD-R once", “transfer to a specific user group” etc.
  • US patent no. 5,629,980 discloses a system for controlling use and distribution of digital works.
  • Usage rights are associated to the digital work, the usage rights defining how a digital work can be used and distributed by a buyer of the work.
  • Digital works are stored in a repository. A repository will process each request to access a digital work by examining the corresponding usage rights.
  • Digital work playback devices coupled to the repository containing the work are used to play, display or print the work.
  • An object of the present invention is to provide a system and a method by which it is possible for a proprietor of copyrighted content and/or a content distributor to attract users to gather limited digital rights to the copyrighted content.
  • Preferred embodiments are defined by the dependent claims.

  • the system further comprises processing means arranged to convert the limited rights into an unlimited digital right, when receiving an instruction in accordance therewith.
  • the unlimited digital right gives a proprietor of the unlimited right access to the content an unlimited number of times.
  • the invention is based on the idea that a mechanism is introduced, by which it is possible to convert limited digital rights, which gives the proprietor of the digital rights access to the content a limited number of times, into an unlimited digital right, provided that the number of accesses associated with the limited right is sufficiently high. It is possible to convert either a single limited right which allows a given limited number of accesses, or a number of limited digital rights which together allow the same given limited number of accesses as the single limited digital right, into an unlimited digital right. In other words, one single limited digital right giving its proprietor the right to access the content, for example, 50 times can be converted into an unlimited right. Alternatively, 50 separate limited digital rights each giving its proprietor the right to access the content one time can be converted into the same unlimited right.
  • the limited digital rights might have been drawn up in such a way that each of the limited rights allow the proprietor of the respective right a different number of accesses. For example, 10 single limited digital rights giving its proprietor the right to access the content 2 times together with 5 single limited digital rights giving the proprietor the right to 3 accesses and one single limited digital right giving the proprietor the right to 15 accesses can be converted into an unlimited right. The total number of accesses is still 50.
  • an agreement must be made on how many accesses that is required in order for a conversion of limited digital rights into an unlimited right to be effected. Alternatively, this is agreed upon in advance.
  • the above described concept is advantageous since if a proprietor of limited rights associated with a digital content holds a sufficient number of limited rights, he/she is allowed to convert these limited rights into an unlimited right.
  • the proprietor of the copyrighted content and or the content distributor can thereby attract users to, for example, surf in to sites on the Internet by in return offering limited digital rights to content, or to buy media such as magazines, CDs ad DVDs to which rights are attached.
  • the user knows that if she collects a sufficient number of limited rights, she is awarded with an unlimited right.
  • the above described concept can preferably also be employed in advertisement, wherein potential customers can be offered limited digital rights when being exposed to the advertisement.
  • the limited digital rights can be distributed on many types of media, for example as computer readable stickers (e.g. RF tags) on magazines, as binary files via the internet, as samples comprised in CDs or DNDs etc. This has the advantage that the sale of these media can be promoted by means of the attached limited digital rights.
  • the digital content and the associated limited digital rights are stored at a server of a digital content provider and the conversion of limited rights into an unlimited right is performed at the server, when the server receives a converting instruction from a device with computing capabilities operated by the proprietor of the digital rights.

Abstract

L'invention repose sur l'idée de l'introduction d'un mécanisme permettant de convertir des droits numériques limités, qui donne au titulaire des droits numériques l'accès à l'oeuvre un nombre de fois limité, en un droit numérique illimité, à condition que le nombre d'accès associé au droit limité soit suffisamment élevé. Le système de l'invention est avantageux en ce que, si un titulaire de droits numériques limités associés à un contenu numérique détient un nombre suffisant de droits limités, il/elle est autorisé/e à convertir ces droits limités en droit illimité. Le titulaire du contenu protégé par le droit d'auteur et/ou le distributeur du contenu peut ainsi inciter les utilisateurs à surfer sur Internet en proposant en retour des droits numériques limités, à acheter des supports, tels que des magazines, des CD et des DVD auxquels les droits sont rattachés.
